Abstract
A system and method are disclosed for enclosing electronic equipment in a noiseproofed and ventilated enclosure. This includes supplying air to an enclosure and removing air from the enclosure through acoustic chambers attached to the enclosure. The acoustic chambers can be constructed of materials or be treated with materials that have noise-absorbing or noise-abating properties. In addition, the acoustic chambers can contain baffles that prevent noise that has entered the acoustic chamber from leaving the chamber. And, the system and method can use a cable egress port that allows cables and wiring to pass through the egress port while blocking the transmission of noise through the egress port.
Claims22
A ventilated housing for electronic equipment that at least abates noise generated by the electronic equipment disposed therein, the housing comprising:
- a housing structure that is capable of being closed except for at least one air ingress opening and at least one air egress opening;
- an air intake structure further comprising,
- an intake inlet for receiving outside air therethrough,
- an intake internal chamber in fluid communications with the intake inlet and an intake outlet,
- the intake outlet for exhausting air from the intake internal chamber and passing said air into the housing structure, with the intake outlet being aligned with the housing air ingress opening, and
- at least one intake baffle disposed and positioned within the intake internal chamber such that noise emanating from within the housing structure is substantially abated from exiting through the intake inlet;
- an air exhaust structure further comprising,
- an exhaust inlet having at least a portion that extends into the housing structure, with the exhaust inlet for receiving air passing from within the housing structure, and with the exhaust inlet further having a portion disposed at a first angle to a horizontal plane extending through the housing structure and aligned with the housing air egress opening,
- an exhaust internal chamber in fluid communications with the exhaust inlet and an exhaust outlet,
- the exhaust outlet for exhausting air from the exhaust internal chamber and passing air outside the air exhaust structure, and
- at least one funnel-shaped baffle arrangement disposed and positioned within the exhaust internal chamber, the baffle arrangement including at least two non-overlapping exhaust baffles, each exhaust baffle being separately connected to the exhaust internal chamber and respectively being disposed at a second and third angle to the horizontal plane extending through the housing structure, with the exhaust baffles having lower and upper ends, the separate lower ends being distal to the exhaust inlet and spaced a first predetermined distance apart, the separate upper ends being proximal to the exhaust inlet and spaced apart a second predetermined distance that is greater than the first predetermined distance, the exhaust baffles being disposed such that at least noise emanating from within the housing structure is abated from exiting through the exhaust outlet,
- wherein the funnel-shaped baffle arrangement includes a central axis disposed between the at least two non-overlapping exhaust baffles, and the exhaust outlet is defined by at least one opening lying in a plane substantially parallel to the central axis and substantially perpendicular to the horizontal plane extending through the housing structure;
- noise-abating material disposed on at least a portion of at least one of the intake baffle, the funnel-shaped baffle arrangement, internal walls of the intake internal chamber walls, internal walls of the exhaust internal chamber walls, or internal walls of the housing structure for abating noise emanating from the housing structure;
- and
- a device associated with the air intake, air exhaust, or housing structures for moving air between the outside of the housing structure and the inside of the housing structure through the air ingress opening.
A ventilated housing for electronic equipment that at least abates noise generated by the electronic equipment disposed therein, the housing comprising:
- a housing structure that is capable of being closed except for at least one air ingress opening and at least one air egress opening;
- an air intake structure further comprising,
- an intake inlet for receiving outside air therethrough,
- an intake internal chamber in fluid communications with the intake inlet and an intake outlet,
- the intake outlet for exhausting air from the intake internal chamber and passing said air into the housing structure, with the intake outlet being aligned with the housing air ingress opening, and
- at least one intake baffle disposed and positioned within the intake internal chamber such that noise emanating from within the housing structure is substantially abated from exiting through the intake inlet:
- an air exhaust structure further comprising,
- an exhaust inlet having at least a portion that extends into the housing structure, with the exhaust inlet for receiving air passing from within the housing structure, and with the exhaust inlet further having a portion disposed at a first angle to a horizontal plane extending through the housing structure and aligned with the housing air egress opening,
- an exhaust internal chamber in fluid communications with the exhaust inlet and an exhaust outlet,
- the exhaust outlet for exhausting air from the exhaust internal chamber and passing air outside the air exhaust structure, and
- at least one funnel-shaped baffle arrangement disposed and positioned within the exhaust internal chamber, the baffle arrangement including at least two non-overlapping exhaust baffles, each exhaust baffle being separately connected to the exhaust internal chamber and respectively being disposed at a second and third angle to the horizontal plane extending through the housing structure, with the exhaust baffles having lower and upper ends, the separate lower ends being distal to the exhaust inlet and spaced a first predetermined distance apart, the separate upper ends being proximal to the exhaust inlet and spaced apart a second predetermined distance that is greater than the first predetermined distance, the exhaust baffles being disposed such that at least noise emanating from within the housing structure is abated from exiting through the exhaust outlet;
- noise-abating material disposed on at least a portion of at least one of the intake baffle, the funnel-shaped baffle arrangement, internal walls of the intake internal chamber walls, internal walls of the exhaust internal chamber walls, or internal walls of the housing structure for abating noise emanating from the housing structure;
- a device associated with the air intake, air exhaust, or housing structures for moving air between the outside of the housing structure and the inside of the housing structure through the air ingress opening;
- and
- a cable egress port the cable egress port further comprising,
- a port structure adapted to be received at a port opening in the housing structure, the port structure including an open back and top, and a removable cover;
- the removable cover being capable of being fixed to the port structure to accommodate a plurality of different sized cables;
- and
- noise-abating material being disposed inside the port structure and on the internal surface of the removable cover such that when the cover is fixed to the port structure, the noise-abating material disposed on the internal surface of the removable cover mates with the noise-abating material inside the port structure to substantially seal at least one cable passing through the port structure into the housing structure such that noise emanating from the housing structure is abated from exiting through the port structure.
